Login tells you who signed in. GrayPass verifies the expected person is still in control before consequential actions happen. We use cognitive biometrics like typing rhythm, cursor movement, scrolling, and response timing alongside session and device context to continuously establish assurance. Before actions like approving a payment, changing admin permissions, exporting sensitive data, or letting an AI agent act on someone’s behalf, GrayPass returns allow, challenge, hold, or deny and produces signed proof tied to that action.

GrayPass checks whether the expected person is still in control before sensitive digital actions and returns an enforceable decision.
The title and description the site itself served, answering 200. Not a cached copy and not the company's directory entry — what was live when we asked.
Founders, titles and bios as the company published them. Photographs are our own copies of the ones on that record, so they do not break when the original link expires.
No investor is drawn from a Form D — the form states how many invested and never who. The one investor on this graph is named because a batch has exactly one.

If you're behind GrayPass: acceptance into a YC batch is one of the few weeks a young company gets looked up by people who matter — investors, other founders, press. FoxPlug turns the commits, deploys, and releases you're already making into that story automatically, so anyone who looks finds something current. GetFoxChat puts a guide on your own site so the people YC's own page just sent you don't read one line and leave.
Sourced from the company's Y Combinator directory entry, and from the company's own site, read directly on 2026-09-20 (graypass.org).
